چکیده
|
The aim of this study is to introduce the new subclasses of bi-univalent functions coupled with subordination in the mirror of (p, q)-analogue of the modified sigmoid function in the unit disc u = {z ∈ c : |z| < 1}. the first two immediate taylor-maclaurin coefficients for the function belonging to these newly introduced classes are obtained. the results are new and a number of corollaries are developed by varying the parameters involved.
